A powerful advocate, Jane Goodall worked tirelessly to improve the lives of all animals and the environment. We are incredibly grateful for her and her lasting legacy that will continue and inspire others to make the world a better place for all living beings.

Chimp Haven is celebrating 30 years of sanctuary for chimps retired from NIH research. Watch their video about Rita and Teresa, the first chimps to arrive at the sanctuary. AAVS is grateful to play a small role in helping with grants through our Sanctuary Fund.

The GAO released a report focused on organ-on-a-chip tech that uses human cells to simulate organ function and are more relevant than animal tests. Challenges that need to be addressed to advance OOCs, including limited access to high-quality human cells. www.gao.gov/products/gao...

In "Animal Emotions," Mark Bekoff and Jane Goodall write about the cruelties dogs endure for research. It starts before they even enter the lab.

#WorldDayforAnimalsinLabs is a day to expose the tremendous suffering mice, rabbits, dogs, and other animals are forced to endure in #experiments. Share this post so others are aware and visit aavs.org/action-center to urge change that helps animals, not hurts them. #HumaneScience #animaltesting

It's #WorldDayforAnimalsinLabs and we want to recognize the suffering that over 105,000 #primates endure in #experiments. They are used in neuro research, vaccine testing, and #infectiondisease studies. Primates are wild animals - not lab tools! #animaltesting #vaccines #humanescience #vaccines

Farmed animals are are used in invasive research that causes immense suffering. In 2023, 51,800 pigs were used in research, 71% in experiments causing pain & 11,500 sheep were used, with over 51% being used in procedures causing pain. #WorldDayForAnimalsInLabs #animaltesting #humanescience

World Day for Animals in Labs is tomorrow! Over 125,000 rabbits were used in labs in 2023 for chemical testing, models of disease, and to produce polyclonal antibodies. Rabbits are companion animals, not lab tools!

We love #beagles because they're friendly & docile, which is also why they're used in experiments. Over 47,200 dogs suffered in labs in 2023 to study heart & lung disease, cancer, and orthopedics, as well as in toxicity testing. www.aavs.org/dogs. #WorldDayForAnimalsInLabs #beagles #animaltesting

#WorldDayforAnimalsinLabs is April 24! The most used animal in experiments are #mice - as many as 100 million suffer in labs, but are not protected by the #AnimalWelfareAct like other animals. #purposebred #geneticengineering #diseasemodels #animaltesting #humanescience aavs.org/animals-scie...

#WorldDayforAnimalsinLabs is less than a week away! We'll be posting through April 24 about the use of animals in science and how to help. Please share our posts.The more people are aware, the more who will care! aavs.org/animals-science #animaltesting #humanescience #alternatives #NAMs #animals
